What Are High Definition (HD) Glasses?

HDTV (High Definition Television) has been getting media attention for several years now, and if you go to an electronics store you can see a fairly good selection of HDTV sets today. If you have ever looked at one of these sets, you know that the image they display is sharper and wider -- it is more like a movie screen than it is a TV set! They make the move or TV show you're watching look like a 3-D scene that's happening right in front of you. Wearing HD glasses can generate the same effect.

How does it work?
HD (High Definition) glasses allow the wearer to see 2-demensional images in 3D, through the process of selective refraction (bending of light) through the lens changes the perceived depth of different colors. For example red appears to be in the front in a picture and items that are blue appear to be in the background, with the other colors of the spectrum taking depth positions in corresponding order (red, orange, yellow, green and blue).

Dark blue and black backgrounds are great for viewing with HD glasses. This is probably why so many underwater scenes and space scenes produce excellent 3-D images. Bright florescent colors, as well as mixed tones such as brown, work well too!

What are some uses?
The ChromaDepth® HD glasses that we sell are generally used for print and laser light shows. HD glasses can be used for all types of viewing, from looking at freehand 3D drawings to watching TV, video, and movies. The ChromaDepth® process encourages fantastic 3D illusions without compromising the quality of the image when viewed without the glasses. These glasses work well for use with printed images, books, UV light/fluorescent paints, magazines and brochures.

ChromaDepth® HD glasses can be used to conduct Earth science hands-on activities by having the students draw underwater geologic scenes or scenes of water flowing in a river channel or a valley with mountain ranges on both sides. Also selective refraction of light, color and depth perception are just a view of the topics that would be ideal to study using HD glasses.

These glasses are inexpensive which means they can be distributed to each child in a class to take home as a hands-on project to try and duplicate the activities demonstrated in class. Great for science fair projects and home schooling. Also ChromaDepth® HD glasses make ideal premiums for distribution by school admission officials when they conduct open-house tours of the their schools.

HD glasses comes complete with easy to follow instructions, an explanation of how the glasses work and a series of suggested activities for their use.
